Kim Kardashian has thousands of trolls, but no one trolls her better than her brother, Rob. Rob Kardashian trolled Kim Kardashian’s lingerie Instagram photo, and now he’s officially our favorite Kardashian. Here’s what happened: Kim took to her Instagram on Saturday, August 15, to post a photo of her family dog, Sushi. The picture featured the Keeping Up With the Kardashians star in gray Skims tank top and underwear as she held the dog close to her.
